9 Claims. 3

This invention relates to roofing and, particularly, to that type of roofing composed of flexible sheet material so cut as to simulate, when laid, the appearance of individual shingles.

One difficulty encountered in many types of sheet roofing of this character is that the edges of the shingle tabs tend to warp due to the heat of the sun, or are often turned up by the wind.

It is therefore an object of the present invention to provide sheets of roofing elements of this character which include means for locking the exposed portions of the shingle tabs so as to prevent their becoming loosened by the wind, or warned by moisture and heat.

Another object of the invention is to provide an improved locking means for shingles of character.

Still another object of the invention is to provide a roofing of this character which will not leak when laid.

A further object of the invention is to provide roofing of this character which will present an improved and attractive appearance.

A still further object of the invention is to pro-- vide roofing of this character which readily lends itself to a variety of attractive designs.

Another object of the invention is to provide roofing of this character which may be medially cut by a cutting machine and rolled it bout separation along the cut so that each part of the original strip be used and the shingle tabs will be protected in the package.

Still another object of the invention is to provide roofing of this character which is relatively easy to apply.

Another objectoi the invention is to provide roofing of this character which may be made of plastic material.

Further objects and advantages of the invention will be brought out in the following part of the specification.

Referring to the drawings, which are illustrative purposes only,

Fig. i is a plan View showing ,a portion of a sheet of roofing embodying the present invention;

Fig. 2 is a plan view showing a portion of laid roof embodying the present invention;

3 is a section taken on the line 3--3 of Fig. 5 shows still another alternative 5 nt thereof.

Ref rring to Figs. 1,2 and 3, there is shown roofing of the strip type, comprising a body portion 5 5? having a straight marginal side edge M. The other marginal side portion is cut to provide alternate recesses, indicated generally at 52, and shingle tabs, indicated generally at Each recess is hounded by a straight side it extending transversely of the body it} and a short straight edge extending parallel to the edge H. Oppositely the side it there is an outwardly extending side portion it which is parallel to the side and an inclined side portion I! which diverges from said side i Q. From the outer end of the diverging side portion I! there is a laterally extending side portion i8 which is also parallel to the side it.

The tab thus formed by cutting out the recesses has an outwardly extending nortion it with parallel sides which are bounded b the edge and a portion of the edge a portion which is bounded by the edge i? which converges with respect to the adjacent edge is of the shingle and another portion of the edge i l, and terminates at its outer end in a tongue 25 which is bounded by the edge It and the remaining portion of the edge i i. The free end 2'2 of the shingle tab is substantially parallel with the edge H.

Adjacent the deepest part of each recess is a slot 23 in the body portion it which extends diagonally relative to the edge H. The slots 23 are of sufficient length to receive the tongues 2! of the shingles, and when the strips of roofing are laid with the shingle tabs staggered, as shown in Fig. 2, the tongues 2! and a corner portion of the part of the shingle tabs-arc received in the slots so that the exposed shingle presents a pointed appearance at its lower extremity.

In laying the roofing astarting strip 2 having diagonal slots 23, is put down first at the lower edge of the roof and secured by nails 25 of suitable character, which are Well known in the roofing art. The nails may be spaced approximately 52 inches apart at the top, or any other suitable distance, said nails being disposed adjacent the straight marginal edge i of the strip. If desired, nail holes 26 may be formed in the roofing strip when it is out.

After the starting strip is laid, the next adjacent strip is laid and nailed, said strip also having the prepunched nail holes .26, and the tongues 2! then inserted in the slots 23 of the starting strip. This procedure is then followed for succeeding strips, the tongues 25 of each added stri being inserted in the slots 23 of the previously laid strip. It is to be understood that the strips are laid so as to stagger the shingle tabs for alignment with the notches of the preceding strip.

When the roogng is laid, the nails of a lower strip are covered by the body portion ill of the strip immediately above it, and the slots of the strips are under-laid by the body portion id of the strip immediately below it. Thus, water is prevented from penetrating through the laid strips and an attractive design is presented.

Due to the length of the tabs 22, and the additional amount of the portion of th shingles which extend through the respective slots because of the diagonal slot, a secure locking of the shingles is provided which will prevent said shingles from being upturned or twisted by the wind, and will also prevent Warping of the shingles under the influence of heat and moisture.

Referring to the arrangement shown in Fig. 4, the shingle tabs 28 of the shingle strip have an irregular outline and are separated by recesses 29 which also have an irregular outline, being defined by the adjacent edges of the shingle tabs. Each shingle tab erminates in a pointed portion 30 which, when th roofing is laid, is adapted to be received in a diagonal slot 23. The pattern of the laid shingles of this configuration presents a futuristic appearance, as brought out in said Fig. 4.

Referring to Fig. 5, there is shown another alternative arrangement wherein the serrated marginal portion includes recesses between longitudinally spaced shingle tabs 3%, said tabs having pointed ends 37 which are received in vshaped slots in the body portion iii. The slots 35 are cut in the body portion adjacent the recesses 35. This arrangement of the shingles, together with their particular shape, provides still another pattern when installed on a roof.

The roofing may be made of any suitable material that is flexible, tough and waterproof. If desired, the shingle strips may be made of a plastic material which is also fire retarding and which may be provided in various colors. An example of such material is Vinylite, although other types of plastic or other suitable roofing material may be used. The roofing strips may be all of one color for a roof, or they may be of various colors so as to provide a vari-colored roof pattern.

The roofing may be easily applied and no cement is needed for securing the shingle tabs or other parts. In 1 act, the application is relatively simple and maybe rapidly made.

It is to be understood that the slot 23 shown in Figs. 1 to 4 may be inclined in the opposite direction in the case of some designs.

I claim:

1. In a shingle strip formed of flexible material, comprising: a body portion having one substantially straight marginal edge, the other marginal side being so shaped as to provide alternating recesses and shingle tabs of reduced size adjacent their free ends, said body portion having slots adjacent the respective recesses, extending diagonally with respect to said straight edge, the free end portions of the shingle tabs being received in respective slots of an underlying strip.
